Re^3: NonMoose and (clean) inheritance

Builders are just generally a better idea than defaults. (MooseX::Manual::BestPractices even tells you so.) They give you a nice clean way to override the behaviour in subclasses.

If you use Moo or MooseX::AttributeShortcuts then you can even do:

has foo => (is => 'ro', builder => sub { ... });
[download]

... and it will automatically get "translated" to:

has foo => (is => 'ro', builder => '_build_foo');
sub _build_foo { ... }
[download]

... so builders can be just as convenient as defaults are.

use Moops; class Cow :rw { has name => (default => 'Ermintrude') }; say Cow->new->name

Thanks for the link of Moose best practices. I didn't know about that one! It's true that builders are preferred over defaults, but it also specifies "However, do use a default when the default is a non-reference.." which happens to be the case here. But hence, for now your solution with builders is the best I have... -- ecocode	[reply]
